Swift的NSURLRequest问题

Question

我想用Swift在WebView中显示一个网站。 这是我的代码： '？NSURL'

import UIKit 
import WebKit 


class ViewController: UIViewController { 


    @IBOutlet var containerView : UIView! = nil 
    var webView: WKWebView? 

    override func loadView() { 
     super.loadView() 

     self.webView = WKWebView() 
     self.view = self.webView! 
    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     var url = NSURL(string:"http://www.google.de/") 
     var req = NSURLRequest(URL:url) 
     self.webView!.loadRequest(req) 
    } 

} 

在var req = NSURLRequest(URL:url)我得到一个错误，

“值可选类型的不打开;你的意思是使用“！”....“

如果我添加！并运行它，我得到了一个运行时错误，

“这一类不是键值为重点的浏览器兼容的编码，”

import UIKit 

class ViewController: UIViewController { 

    @IBOutlet weak var wv: UIWebView! 


    func loadUrl(){ 
     wv.loadRequest(NSURLRequest(URL: NSURL(string: "http://www.google.de/")!)) 
    } 
    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 
     loadUrl() 

    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    }
